Art.Nr.: HD9008TRRProduktbeschreibung
dual, passive, meteorological microprocessor transducer for humidity and temperature,
4 mA to 20 mA output
general information:
HD9008TRR is a single block microprocessor transducer for humidity and temperature, temperature is configurable. The HD9008TRR is a passive transmitter with a 4 mA to 20mA output and 10 V DC to 40 V DC power supply. The sensors are mounted at the end of a plastic tube: a capacitive humidity sensor and a platinum temperature sensor (100 Ω @0°C).
The instrument can be reprogrammed by means of a key, and no jumper or potentiometer actions are required. The humidity input can be recalibrated by using two saturated solutions: the first one at 75 %, the second one at 33 %; the elative humidity range 0 % to 100 % r.F. r is fixed, 4 mA correspond to 0 % r.F., 20 mA equal 100 % r.F.
The temperature standard configuration is –40°C to +80°C, corresponding to 4 mA to 20 mA. The user can configure the temperature output in ranges different from the standard one by means of a Pt100 simulator or of a set of fixed resistances, provided that it is included within the -40°C to +80°C range and shows a minimum amplitude of 25°C. Two LEDs give alarm indications (temperature exceeding set range, sensor breakage or shortcircuit) and help the operator when programming.
An out-of-standard temperature operating range can be requested when placing the order.
Important warning: the probes work in the -40°C to +80°C temperature range. Outside of this range data are not correct; electronics are designed to operate within this range.
